I know Dillon said something about using different materials for the roof and side of the greenhouse...but what I'mgonna build ( with the hope of keeping operation costs as low as possible) is a passive green house where only the south facing wall is see thru the other three sides are insulated to keep the warmth in.so it's only gonna be solexx or polycarbonate angled up according to my latitude so it gets optimal sunlight in the short winter days.

Hello everyone,I never participated in a forum in my life and english is not my first language so forgive me in advance for any étiquette faux pas I am considering building a couple of passive energy greenhouses here in northern New-Brunswick (cold and huge snow loads). It's gonna be a two step project first part is gonna be a small garden center deal with flowers and plants in the springtime. Second part will be an aquaponic system where I hope to be able to produce fresh vegetables and some fruit year round,the problem is...Canada . I am considering solexx as a material for it but I'm not sure if the diffused light is gonna conteract the natural heat gain I would get from a transparent covering?! I want to use black water barrels as heat sinks to store the sun's energy,I can't seem to find any info about this in particular anywhere,and I can only guess it would still be better to use solexx?! Thanks
